This invention relates to closures especially adapted for the ends ofrolls of sheet mate rial, wherein the accessories such as nails, ce'ment and the like used in conjunction with the material will beefiiciently retained within the rolls during shipment and has for theprimary object, the provision of a device of the above stated characterwhich may be easily and quickly applied and will effectively seal theends of the roll to prevent displacement of the accessories therefromand the admission of rain or foreign matter thereto.

Another object of this invention is the pro vision of securing means forthe closures which will be self-locking and which may be easily andquickly detached from the roll when desiring to remove the closures soas to obtain the accessories.

A further object of this invention is the provision of a closure plug ofthe above stated character which will be simple, durable and efficientand which may be manufactured and sold at a comparatively low cost.

With these and other objects in view, this invention consists in certainnovel features of construction, combination and arrangement of parts, tobe hereinafter more fully described and claimed.

For a complete understanding of my inven- 33 tion, reference is to behad to the following description and accompanying drawings, in whichFigure 1 is a perspective view illustrating a roll of sheet materialhaving its ends closed by closure plugs constructed in accordance withmy invention.

Figure 2 is an enlarged sectional view illustrating the same and showingthe accessories confined within the roll.

Figure 3 is a perspective view illustrating one of the closure plugswith a self-locking fastener applied thereto.

Figure 4 is a plan view illustrating the blank of a fastener.

Figure 5 is an end view illustrating a slight modification of myinvention.

Figure 6 is a perspective view illustrating a modified form of fastener.

Figure 7 is a detail sectional view illustrating another modified formof my invention.

Referring in detail to the drawings the numeral 1 indicates a roll ofsheet material which may be of any desired character and when shippingand selling such material it is desirable by the seller to furnishaccessories for the material such as nails, cement and the like andthese accessories are placed within the roll as shown in Figure 1 and toprevent their accidental displacement and to protect the accessoriesfrom weather elements, closure plugs 2 are provided and are inserted ineach end of the roll as clearly shown in Figure 2.

The closure plugs are identical in construction and reference to onespecifically is thought sufficient for both. A plug 2 includes a body 3having an annular flange 4 at one end to engage the roll of sheetmaterial 4 as clearly shown in Figure 1 to effectively seal the spaceformed within the roll. The inner end of the plug 3 is tapered as shownat 5 and secured to the inner end of the plug is a fastener 6 whichprojects beyond opposite sides of the plug and has formed thereon annularly disposed tines 7 overlying the bevelled face 5 and having theirfree ends biting into the material of the roll as clearly shown inFigure 2 and which will prevent the removal of the closure plug from theroll. The plug 2 is provided with an opening 7 extending centrallytherefrom and the fastener 6 overlies the inner end of the opening andis secured to the plug by small nails or like fasteners 8 whereby on theinsertion of a suitable instrument 9 through the opening 7 the fastenercan be removed from the inner end of the plug freeing the plug that itmay be easily removed from the end of the roll.

As shown in Figure 5 a pair of fasteners 6 may be secured to the innerend of the plug and arranged at right angles to each other. Thefasteners 6 when arranged as shown in Figure 5 are secured to the innerends of the plug by the fasteners 8 and overlie the inner end of theopening 7 whereby the instrument 9 is inserted through the opening andboth fasteners will be detached from the plug.

As shown in Figure 6 the fastener 6 may have tines 10 struck uptherefrom for the purpose of being inserted in the end of the plug forretaining the fastener thereon. It is to be understood that the fasteneris applied to the end of the plug by the inserting of the plug in theroll and owing to the an-- nularly related tines 7 the plug can beeasily inserted in the roll but will be prevented from being removedtherefrom due to the tines biting into the material of the roll.

Referring to Figure 7 the plug 11 is of 1101- low formation andpreferably constructed of wood and includes an outer flange 12 and aninner wall 13 centrally apertured as shown at 14: and also provided withopenings located adjacent the aperture 14. The body of the plug 11 istapered as shown at 15 to permit the tines on the fastener applied tothe inner Wall to bend inwardly when inserting the plug in the roll. Thefastener is secured to the inner wall 13 by the tines 10 insertedthrough the openings adjacent to the central aperture 14 and bent overas clearly shown in Figure 7. By inserting the instrument 5) through theaperture 14 against the fastener, the tines 10 may be caused tostraighten and pass through the apertures of the inner wall and therebydetach the fastener from the plug.

While I have shown and described the preferred embodiment of myinvention it will be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of the invention, as claimed.

Having thus described my invention, what I claim is:

1. A closure for rolls comprising a plug to be inserted in the end of aroll and having an opening therethrough and provided with tapered innerend, a fastening strip detachably secured to the inner end of the plug,tines at the ends of the strip for biting into the roll and overlyingthe bevelled inner end of the plug so that said tines may fiex inwardlywhen the plug is inserted in the roll, said strip overlying the openingwhereby an instrument may be placed in engagement tliierewith fordetaching said strip from the p ug.

2. A closure for rolls comprising a plug to be inserted in the end of aroll and having an opening therethrough, a fastening strip havingtongues struck up therefrom and driven into the inner end of the plug,tines on the ends of the strip to bite into the roll, said stripoverlying the opening whereby an instrument may be placed in engagementtherewith for detaching said strip from the plug.

3. A closure for rolls comprising a hollow body for insertion in the endof a roll, a flange formed on the outer end of the body to engage theend of the roll, an inner wall formed on the body and having a centrallyarranged opening and a pair of apertures, a fastening strip engagingsaid wall, tines struck up from the strip and extending through theapertures and bent to engage the wall, tines at the ends of the stripfor biting into the material of the roll, said strip overlying thecentrally arranged opening, whereby an instrument may be placed inengagement therewith for?
